In the ever-evolving realm of cybersecurity, a significant and emerging threat looms on the horizon, known as "Harvest Now, Decrypt Later" (HNDL). This threat is particularly concerning as quantum computing advances, promising to outstrip the capabilities of traditional cryptographic methods. With quantum computers on the brink of breaking current encryption, the data we consider secure today could be easily decrypted in the future. This article delves into the intricacies of HNDL, its potential impact on various industries, and the country’s most likely to be affected.
What is "Harvest Now, Decrypt Later (HNDL)"?
The "Harvest Now, Decrypt Later" strategy involves cyber adversaries collecting and storing encrypted data today with the intention of decrypting it once quantum computers become sufficiently advanced. Current encryption methods, such as RSA and ECC, are based on mathematical problems that are nearly impossible for classical computers to solve within a reasonable timeframe. However, quantum computers, with their immense processing power, could solve these problems, rendering today's encryption obsolete. Today, a huge amount of stolen information is lying in foreign databases. They are ready to be exposed in the next few years with the imminent arrival of quantum computers. It’s time for governments and enterprises to step up. They need to be quantum-ready and develop a crypto-agility strategy.

How QNu Labs Helps Address the Harvest Now, Decrypt Later (HNDL) Threat
With the acceleration in digital transformation, there is an increase in the likelihood of data breaches. Today, nations are developing smart cities, autonomous cars, and other edge devices where vulnerabilities can open up at many points. We live in a world where codes run power plants, industries, and more. But this kind of digital transition demands upgradation of data security too.
Data is a critical part of digitization; nation-state hackers pose a threat to even the best cybersecurity systems since they can steal vital information, including drug blueprints, government confidential information, banks’ sensitive data, enterprise R&D information, and nuclear blueprints. Cybercriminals are continuously finding ways to incorporate sensitive information into their networks across the globe. Hackers working for China, Iran, Russia, North Korea, and other nations are spying and stealing data and harvesting it for the future.
Some past attacks involving highly sensitive data include the USA escalating online attacks on Russia’s power grid and the Stuxnet worm on Iranian nuclear facilities. In the battles of cybersecurity and cybercriminals, the game changer is coming in the form of quantum computers, which can break conventional cryptography in no time. Any encryption built on mathematical complexities (which include RSA, DSA, ECDH, and other variants of ciphers) is highly vulnerable to quantum attacks. Encryption protects everything from sensitive information to the operation of power plants, dams, stock markets, defence secrets, and government sensitive data.
Data tapping is not new. Hackers are motivated to tap encrypted data and collect substantial amounts of it while waiting for quantum computers to crack the keys. If hackers can crack the encrypted keys, it will be the next “data pandemic”.
Quantum Race of Super Powers
China and US are in the race to develop a quantum computer, which can democratize many industries, particularly in the fields of medicine, AI and scientific modelling. Chinese satellites are using quantum cryptography to secure video conferences between continents. Swiss government is also using quantum key distribution (QKD) to protect its national elections and many such applications.
As tons of data is already sitting on cloud, databases can be exposed any time in the near future using a quantum computer. The estimated time is 2-3 years. Are you ready for the next data pandemic?
What organisations can do to be Quantum Ready
- Conduct post-quantum risk assessment
- Diagnose infrastructure of your organization
- Have Crypto Agility to counter quantum attacks
- Ensure your PKI can be migrated to quantum cryptography in no time
- Take a hybrid approach using quantum and classic crypto solutions
- Design quantum-safe infrastructure
Why is quantum cryptography unbreakable?
Quantum Key Distribution (QKD) uses photons to send encrypted keys. Hence, theoretically, they are absolutely unbreakable. Any attempt to eavesdrop will be detected easily and instantly, thereby triggering preventive steps. In today's time, PKI attacks are virtually undetectable. Hence, by using QKD, attempts of eavesdropping and man-in-the-middle attacks can be detected.
As today’s PKIs are based on mathematical computations, the keys can be easily broken using Shor’s or Grover’s algorithms on quantum computers. Theoretically, by using QKD, the keys can be made 100% hack-proof and 100% random as well. Today, protecting data in transit is crucial while PKI lacks in detecting eavesdropping. By using QKD, businesses can detect incidents of eavesdropping and secure data in transit.
